Binge eating disorder (BED) is a common condition in the general population and is more common in individuals with obesity. The later timing of food intake has been associated with an increase incidence of obesity. The purpose of this study was to evaluate the relationship between circadian chronotype and BED in a population of individuals with obesity. The sample consists of a retrospective review of 170 subjects presenting to an obesity medicine clinic who had been clinically evaluated for BED and chronotype.

No significant correlation was found between BED and a late chronotype in this population. In a secondary analysis no significant difference in degree of weight loss was related to the presence or absence of BED or an earlier or later chronotype. This retrospective study does not support the relationship of binge eating disorder and circadian chronotype.
